Finished the STS install on my Trailblazer SS today. Still need to install the MSD Boost-a-pump, but the MSD instructions SUCK. Any pointers for a newbie?

yeah its pretty easy i just hooked it up to my boost control switch ,not the relay and found out which wire powerd up for 3 seconds when i hit the ignition and ground hooked it up and good to go.but to be honest i dont use it my stock fuel pump does fine with the 42# injectors at 12 psi and with the diablo if you have the bigger injectors put your injector slope up like 45-55 points up and only a little power enrichment.

Thanks, I've had a number of people tell me I won't need it. Gonna make sure with some datalogs and prolly either return it or try and sell it.
